The object of the invention is todprovide 4 a perspective view of thelower portion improvements in 'teXtile machinery, and more particularly.in heddle frames for looms. h

5' Another. and 'more specific object is to provide in heddle framesmeans for stiffening the oppositely positioned rails, and for,

supporting the heddle bars with respect to said rails and to one anotherat one or more points intermediate of their ends, where ing and fixingthe relation of intermediate portions of oppositely positioned heddlebars to the rails of the heddle frames, and for connecting such portionsof said bars to each other, and thus indirectly connecting said railstogether to stiffen the frame, in addition to stay rods which may bepresent and in use for such latter purpose.

Still another and more specific ob ect is members secured to theopposite rails of a heddle frame and disengageably connectedi to therespectively adjacent heddle bars, to-

' gether with a rod having bifurcated hookshaped end portions adapted,upon drawing the central portions of the oppositely dis posed rails andbars towards each other, to

straddle said members and engage said bars in hooked relation, afterwhich the resiliency of said rails and bars returns them to V vicehasbeen constructed to lnsure this their original parallel positions.

lVith these of construction and" operation which are com an i11 drawin sin which Fi .1 is a front elevation of a heddle frame comprising top andbottom rails and heddle bars connected by tie rods operating inaccordance with and embodying features compris 0 tary portion of Fig. 1in elevation; and Fig.

to provide a pair of hooks or hook-shaped and other objects in mind, thepresent invention comprises further details.

fully brought out in the following description when read in conjunctionwith the acas. the case may be. consists primar ly n a central shankpork sitely positioned top and bottom rails 1 and 2, connected at theirends by any suitable -means such asstraps 3. Heddle supporting bars 4and 5 extend longitudinally of the frame parallel with and spacedslightly from the neighboring frame rails 1 and 2,

and operatively supporting a bank or series of heddles. 6, which, areattached thereto in any well known manner.

l/Vhile not necessary to the operation of the present invention, a stayrod 7 is shown -f asextending between and in the plane of the rails land 2.- -This rod is detachably secured to said rails,-and removablyreceives adjacent portions of thebars 4 and 5 in any suitable manner, asfor instance by means ofa construction illustrated in de tall 1n a,co-pendlng appl cation whlch resulted in Letters Patent N0."1,701,520.But,

as before stated, the position, shape and even :the'presence of thisstay rod is inde-T' pendent of the tie rod or rods comprising thepresent invention. A

The rails 1 and 2 are satisfactorily maintained in adefinitespacedrelation by the stay rod-referred to, but the presence of such rod doesnot-insure the desirable fixed relation that should exist between theheddle bars l and 5; as well between said bars and said-rails.Therefore, the present deprevious deficiency, andyet to be applicable toand detachable from a heddle frame without interfering materially with.the positions and operation of the heddles, and

permitting the shifting of such heddles'f whenever desired. To each ofsand rails there is secured in any suitable manner the threaded portion8 of a hook which also comprises a shank 9 angularly disposed withrespect to said 'threaded portion, and a hook-shaped free end portion 10adapted to normally receive one of the adjacent heddle bars 4 and 5, Thetie rod proper tion 11, having bifurcated heads 12, providing spacedparallel fingers, each of which is recessed transversely inwardly fromone lateral edge portion at 13 and terminates in a hook-shaped free endportion 14, also adapted to engage the adjacent heddle bar 4 or It isobvious that the shank 11 of the tie rod may comprise a single thicknessof any suitable cross section, However, in order to produce commerciallya highly efiicient shape of tie rod, it has been found excellentpractice to form the same from two parallel strips of relatively thinmetal rods, secured together in unitary relation throughout theircentral shank by any suitable form of rivets 15, welding, or the like,and separated at their bifurcated portion (as shown in Figs. 1 and toform in etlect a pair of spaced parallel hooks which are adapted to bepositioned upon the opposite sides of the adjacent fixed hook member 10by straddling the same.

In order to apply this improved tie rod in a heddle frame, the stay rod7 if present must be at least loosened and removed at one end from theadjacent rail, after which the rails l and 2, together with theirneighboring heddlebars t and 5, may be sprung towards each other untilone of the double hooked ends of the rod 11 is passed over the upper bart, for instance, and upon the opposite sides of the upper fixed hook 10,after 1 which the lower double hooked portion of said tie rod is passedover the lower heddle bar 5, whereupon releasing said rails and adjacentbars, their resiliency returns them into their original parallelrelation and thereby draws the bar 5 into the lower hooked end portionof said tie rod, after which the stay rod 7 can be replaced. In order towithdraw said tie rod from the heddle frame for the purpose oflongitudinally adjusting or replacing the heddles, or for otherpurposes, the foregoing procedure is reversed, and the rails and barsare drawn towards each other so as to disengage first one and then theother of the hooked end portion-sot the tie rod from said bars, in eachcase the stay rod 7, if present, having to be first disconnected andthen replaced in operative position after the desired adjustment hasbeen effected.

Having thus described my invention, what'I claim and desire to protectby Letters Patent of the United States is 1. The combination of a heddleframe,

comprising spaced parallel rails and heddle i bars, with membersnormally fixed to said rails and engaging said bars, and a laminatedmember comprising a pair of rods secured together at their centralportions and a spaced apart at their end portions, whereby the adjacentends of said rods are adapted to straddle the respective first membersand the adjacent end portions themselves spaced apart and adapted tostraddle one of said first members and be detachably secured to theadjacent bar, the opposite end of one of said rods being normallysecured to the other of said bars, said rods thereby maintaining apredetermined distance between said rails and said bars. I

In testimony whereof I have aflixed my signature.
